Abstract: 1,206,529. Oxidized starch. CORN PRODUCTS CO. 11 Dec., 1968 [21 Dec., 1967], No. 59029/68. Heading C3U. An aqueous slurry of raw granular starch is treated with a mixture of a hypohalogenous acid and a halogen, followed by treatment with different less powerful, oxidizing agent. The pH during treatment may be pH 1-6, and the final product adjusted to pH 5-7, preferably by use of an alkaline potassium compound, followed by adjustment to 15-30% solids, filtration and drying to a moisture content of less than 14% by weight. The use of hypochlorous acid with chlorine, followed by treatment with H 2 O 2  is exemplified. The acid and halogen may be derived from (i) an alkali metal hypohalite, (ii) electrolysis of an acidic halide-containing starch slurry or (iii) by addition of halogen to an acidic starch slurry. Many starches, including high amylose and starch-containing cereal flours may be so treated. The product is useful as a batter mix for foodstuffs, and exhibits increased adhesion thereto.

Filed: 1970-12-15
Abstract: 1307560 Copying by scanning MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 Dec 1970 [15 Dec 1969] 59475/70 Heading H4F  A facsimile system comprises a cathode-ray tube 12 provided with a fibre-optics faceplate 14, the electron beam 18 striking a phosphor layer 16 on the faceplate 14 to produce a flying spot which scans the information medium 20 through the faceplate 14 in both read-out and read-in modes. In the read-out mode the electron beam 18 is scanned over the part of the phosphor layer 16 below inclined face 24 of the faceplate 14, the information medium 20 being fed in the direction 26 by a capstan 70 and guided out of the apparatus by guide 74. The light from the flying spot reflected from the information medium 20 is picked up in a photoelectric converter 28 and the signal from the photo-electric converter 28 is fed via a preamplifier 46a and process amplifier 50 where it is superimposed on a D.C. voltage, mixed with synchronizing pulses from a synchronizing pulse generator 52 and undergoes γ-correction and aperture correction to output terminal 54. The process amplifier is controlled by a read-out control 78 connected to a photo-detector 82 which senses the presence of the information medium 20 by the light from a lamp 84 being cut off. The read-out controller 78 also controls the motor 72 to drive the capstan 70. The synchronizing pulse generator 52 drives a parabolic wave generator 58 which is connected to the focusing element 36 of the cathode-ray tube 12 via a focusing amplifier 68. Outputs from the pulse generator 52, sawtooth wave generator 56 and parabolic wave generator 58 are fed to an intensity control 64 to cause the electron beam to undergo shading correction through the first control grid 34 of the cathode-ray tube 12. In the read-in mode the electron beam 18 is scanned over the part of the phosphor layer 16 below inclined face 22 of the faceplate 14, the information medium 20 being guided by guide 74 into a developer 98. The signals are passed into an input terminal 90 and then via pre-amplifier 46, image signal amplifier 94 to intensity control 64, and also to a synchronizing pulse separator 92 which feeds the sawtooth wave generator 56 and parabolic wave generator 58 and also drives a read-in controller 96 which synchronizes the speed of the motor 72 with the sweep rate of the cathode-ray tube 12. In an alternative embodiment the information medium 20 is transported at right-angles to the axes of the fibre optics in the faceplate 14 and two photo-electric detectors are used to pick-up the reflected light, the electron beam scanning only along the edge between the faces 22, 24.
